Available DCN solutions and application differences of these solutions

5

A data communication network (DCN) provides communication channels for NEs that are managed uniformly to achieve remote management and maintenance on the NEs.
DCN solutions are classified into inband DCN and outband DCN. The inband DCN uses service channels provided by managed devices to achieve device management. The outband DCN provides dedicated communication channels to achieve device management for NEs that are uniformly managed.
Huawei provides the following outband DCN solutions:
HWECC solution: When a network is composed of only transmission devices, the HWECC solution is the first choice.
IP over DCC solution: When a network is composed of both Huawei transmission devices and third-party devices that support the TCP/IP function, this solution is the first choice. The solution also applies when the network is composed of only Huawei transmission devices.
OSI over DCC solution: When a network is composed of both Huawei transmission devices and third-party devices that support the OSI over DCC function, this solution is the first choice.
